GPUs Mine Astronomical Datasets For Golden Insight Nuggets

As humankind continues to stare into the dark abyss of deep space in an eternal quest to understand our origins, new computational tools and technologies are needed at unprecedented scales. Gigantic datasets from advanced high resolution telescopes and huge scientific instrumentation installations are overwhelming classical computational and storage techniques.

This is the key issue with exploring the Universe – it is very, very large. Combining advances in machine learning and high speed data storage are starting to provide hitherto unheard of levels of insight that were previously in the realm of pure science fiction. Using computer systems to infer knowledge …

Another Step In Building The HPC Ecosystem For Arm

Many of us are impatient for Arm processors to take off in the datacenter in general and in HPC in particular. And ever so slowly, it looks like it is starting to happen.

Every system buyer wants choice because choice increases competition, which lowers cost and mitigates against risk. But no organization, no matter how large, can afford to build its own software ecosystem. Even the hyperscalers like Google and Facebook, whole literally make money on the apps running on their vast infrastructure, rely heavily on the open source community, taking as much as they give back. So it is …

Pushing Up The Scale For Hyperconverged Storage

Hyperconverged storage is a hot commodity right now. Enterprises want to dump their disk arrays and get an easier and less costly way to scale the capacity and performance of their storage to keep up with application demands. Nutanix has a become as significant player in a space where established vendors like Hewlett Packard Enterprise, Dell EMC, and Cisco Systems are broadening their portfolios and capabilities.

But as hyperconverged infrastructure (HCI) becomes increasingly popular and begin moving up from midrange environments into larger enterprises, challenges are becoming evident, from the need to bring in new – and at times …

Using Ansible to Mitigate Network Vulnerabilities

Even Networks Aren’t Immune

Just like with Windows and Linux servers, networking devices can be exploited by vulnerabilities found in their operating systems. Many IT organizations do not have a comprehensive strategy for mitigating security vulnerabilities that span multiple teams (networking, servers, storage, etc.). Since the majority of network operations is still manual, the need to mitigate quickly and reliably across multiple platforms consisting of hundreds of network devices becomes extremely important.

In Cisco’s March 2018 Semiannual Cisco IOS and IOS XE Software Security Advisory Bundled Publication, 22 vulnerabilities were detailed. While Red Hat does not report or keep track of individual networking vendors CVEs, Red Hat Ansible Engine can be used to quickly automate mitigation of CVEs based on instructions from networking vendors.

In this blog post we are going to walk through CVE-2018-0171 which is titled “Cisco IOS and IOS XE Software Smart Install Remote Code Execution Vulnerability.” This CVE is labeled as critical by Cisco, with the following headline summary:

“...a vulnerability in the Smart Install feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to trigger a reload of an affected device, resulting in a Continue reading

IDG Contributor Network: Will enterprise IoT become BYOD on steroids?

If you thought BYOD was a pain the neck for IT management, strap yourself in.The integration of Internet of Things (IoT) devices in the enterprise is moving beyond the hype into a much more pragmatic and operational phase of planning, execution and service delivery.There’s massive interest and buzz around IoT within companies of every type. This is largely due to the transformative business impact IoT will have. Major business will be transformed, disrupted or out completely when IoT is properly used in the business transformation process.But with IoT solutions comes new demands and a wide range of technologies, many of which will take the enterprise into unfamiliar territory, requiring different analytical skills and management tools. In other words, IoT devices quickly finding their way into to the enterprise will make life a living hell for network managers – far beyond the problems they experienced with BYOD.To read this article in full, please click here

BrandPost: What your network needs for GDPR compliance

There is nothing like a looming deadline to get people motivated. For the General Data Protection Regulation (GDPR), May 25 is that deadline. A sweeping new data privacy regulation, GDPR will soon come into effect across the European Union (EU). In practice, however, it affects any company or organization conducting business or operations in the EU (whether through a physical presence there or offering goods and services to EU residents) that collects and processes EU residents’ data. Its goal is to better protect and empower EU residents’ data privacy, and it represents the most significant change in data privacy laws in more than 20 years. For businesses too, it will be a watershed moment in how they process, handle and manage data, with heavy fines on the table for non-compliance.To read this article in full, please click here

In the IoT world, general-purpose databases can’t cut it

We live in an age of instrumentation, where everything that can be measured is being measured so that it can be analyzed and acted upon, preferably in real time or near real time. This instrumentation and measurement process is happening in both the physical world, as well as the virtual world of IT.For example, in the physical world, a solar energy company has instrumented all its solar panels to provide remote monitoring and battery management. Usage information is collected from a customers’ panels and sent via mobile networks to a database in the cloud. The data is analyzed, and the resulting information is used to configure and adapt each customer’s system to extend the life of the battery and control the product. If an abnormality or problem is detected, an alert can be sent to a service agent to mitigate the problem before it worsens. Thus, proactive customer service is enabled based on real-time data coming from the solar energy system at a customer’s installation.To read this article in full, please click here

Reaction: DNS Complexity Lessons

Recently, Bert Hubert wrote of a growing problem in the networking world: the complexity of DNS. We have two systems we all use in the Internet, DNS and BGP. Both of these systems appear to be able to handle anything we can throw at them and “keep on ticking.”

But how far can we drive the complexity of these systems before they ultimately fail? Bert posted this chart to the APNIC blog to illustrate the problem—

I am old enough to remember when the entire Cisco IOS Software (classic) code base was under 150,000 lines; today, I suspect most BGP and DNS implementations are well over this size. Consider this for a moment—a single protocol implementation that is larger than an entire Network Operating System ten to fifteen years back.

What really grabbed my attention, though, was one of the reasons Bert believes we have these complexity problems—

DNS developers frequently see immense complexity not as a problem but as a welcome challenge to be overcome. We say ‘yes’ to things we should say ‘no’ to. Less gifted developer communities would have to say no automatically since they simply would not be able to implement all that new stuff. Continue reading

Google: A Collection of Best Practices for Production Services

This excerpt—Appendix B - A Collection of Best Practices for Production Services—is from Google's awesome book on Site Reliability Engineering. Worth reading if it hasn't been on your radar. And it's free!

 

Fail Sanely

Sanitize and validate configuration inputs, and respond to implausible inputs by both continuing to operate in the previous state and alerting to the receipt of bad input. Bad input often falls into one of these categories:

Incorrect data

Validate both syntax and, if possible, semantics. Watch for empty data and partial or truncated data (e.g., alert if the configuration is N% smaller than the previous version).

Delayed data

This may invalidate current data due to timeouts. Alert well before the data is expected to expire.

Fail in a way that preserves function, possibly at the expense of being overly permissive or overly simplistic. We’ve found that it’s generally safer for systems to continue functioning with their previous configuration and await a human’s approval before using the new, perhaps invalid, data.

Examples

In 2005, Google’s global DNS load- and latency-balancing system received an empty DNS entry file as a result of file permissions. It accepted this empty file and served NXDOMAIN for Continue reading
